The goal of this website is to serve as a portfolio for all of my designs and experience in the engineering world. It contains a number of relevant projects I have been a part of, and will be updated with my new experiences as they develop. I hope that by leaving this website, you will have learned much more about me as a professional!
I am entering my fourth year of university and have been studying with the full intent to work in aerospace, taking courses in fluid mechanics, thermodynamics, solids and materials, aerospace human factors, and turbomachinery. For the 2024/25 development cycle, I designed and manufactured a high-pressure nitrogen quick disconnect system, which was a complete success and allowed the team to become the first student organization in the US to launch a LOX-hybrid vehicle. For the 2025/26 development cycle, I increased my responsibility and lead a team which developed an entire liquid oxygen feed system, including custom quick disconnects, automatic fill valves, check valves, and integration with GN2 systems and electronics. For this upcoming school year, I look forward to developing a liquid bipropellant engine, leading an expanded team working on LOX and ethanol feed lines, including brand new parts such as a venturi flow meter. During this time, I have also gained considerable experience in industry. In 2025 and 2026 I interned at Ball Corporation and STS Aerospace, respectively. During this work I not only learned and gained experience integral to engineering in industry, but I applied skills in design, manufacturing, data analysis, and process management to leave a lasting impact at each company. All of this has prepared me for full time positions in the aerospace world.
Welcome!
My name is Paolo Maselli, I'm from New Jersey, and I’m a fourth-year mechanical engineering student at Columbia University SEAS. Growing up, I was fascinated by toy rockets and airplanes, always dreaming of being in the clouds and reaching the stars. That early passion has shaped my path. Since arriving at Columbia, I’ve been an active member of the Columbia Space Initiative Rocketry Team and have completed two mechanical engineering internships.
